Method replaceFrom

corpus/java/training/guava/base/CharMatcher.java:753–767

Returns a string copy of the input character sequence, with each character that matches this matcher replaced by a given replacement character. For example: CharMatcher.is('a').replaceFrom("radar", 'o') ... returns "rodor". The default implementation uses {@link

(CharSequence sequence, char replacement)

   * @return the new string

  public String replaceFrom(CharSequence sequence, char replacement) {
    String string = sequence.toString();
    int pos = indexIn(string);
    if (pos == -1) {
      return string;
    }
    char[] chars = string.toCharArray();
    chars[pos] = replacement;
    for (int i = pos + 1; i < chars.length; i++) {
      if (matches(chars[i])) {
        chars[i] = replacement;
      }
    }
    return new String(chars);
